RX23W Group 7. Option-Setting Memory (OFSM)
7.3 Usage Note
7.3.1 Setting Example of Option-Setting Memory
Since the option-setting memory is allocated in the ROM, values cannot be written by executing instructions. Write
appropriate values when writing the program. Examples of the settings are shown below.
 To set FFFF FFF8h in the OFS0 register
.ORG 0FFFFFF8CH
.LWORD 0FFFFFFF8H
 To set FFFF FEF0h in the OFS1 register
.ORG 0FFFFFF88H
.LWORD 0FFFFFEF0H
.ORG 0FFFF7F88H
.LWORD 0FFFFFEF0H
When neither the voltage monitoring 0 reset nor power-on fast startup time is used, the value set in the address
FFFF 7F88h can be FFFF FFFFh.
Note: Programming formats vary depending on the compiler. Refer to the compiler manual for details.
